Description

Technical Field

[0001] The invention relates to the field of dimethyl sulfoxide, in particular to the technical field of catalyst packaging for dimethyl sulfoxide, and in particular to a packaging and sealing detection device for a catalyst for dimethyl sulfoxide production. Background Art

[0002] Dimethyl sulfoxide (DMSO) is a sulfur-containing organic compound. It is a colorless and transparent liquid at room temperature. It has the characteristics of high polarity, high hygroscopicity, flammability and high boiling point aprotic. Dimethyl sulfoxide is soluble in water, ethanol, acetone, ether and chloroform. It is a highly polar inert solvent and is widely used as a solvent and reaction reagent. In addition, dimethyl sulfoxide has a high selective extraction ability and can be used as an extraction solvent for separating alkanes from aromatic hydrocarbons. For example, dimethyl sulfoxide can be used for the extraction of aromatic hydrocarbons or butadiene, as a processing solvent and spinning solvent in acrylonitrile polymerization, as a synthetic solvent and spinning solvent for polyurethane, and as a synthetic solvent for polyamide, fluorochloroaniline, polyimide and polysulfone. At the same time, in the pharmaceutical industry, dimethyl sulfoxide can not only be directly used as a raw material and carrier for certain drugs, but also has anti-inflammatory, analgesic, diuretic, sedative and other effects. Therefore, it is often added to drugs as an active component of analgesics. In addition, dimethyl sulfoxide can also be used as a capacitor medium, antifreeze, brake fluid, rare metal extractant, etc.

[0003] Chinese invention patent application number CN201210419837.0 discloses a method for preparing dimethyl sulfoxide, wherein the catalyst used contains titanium silicon molecular sieve and a carrier, and the catalyst needs to be sealed and packaged for storage.

[0004] Existing packaging sealing detection devices usually place the packaging device in a water tank, extract the air in the water tank to form a negative pressure in the water tank, and judge whether the packaging sealing is good by observing whether bubbles float on the packaging, or judge the sealing of the packaging by detecting whether there is gas seeping from the packaging in the space under a vacuum environment.

The cylindrical key in 109 is slidably matched with the oblique slide groove outside the adjustment ring 204, and the gear ring 109 is driven to rotate by starting the second motor 110. When the gear ring 109 rotates, the cylindrical key and the slide groove on the adjustment ring 204 are matched to drive the adjustment ring 204 to slide downward in the circular hole in the center of the detection carrier 102, and the arc support rod 108 is driven to rotate in the circular hole in the center of the adjustment ring 204 by pressing down the adjustment ring 204, so that the bottom of the arc support rod 108 opens the elastic sealing rubber tube 107, so that the catalyst package can enter from the bottom of the elastic sealing rubber tube 107, and then the second motor 110 is started to rotate in the opposite direction, so that the arc support rod 108 is rotated to the original position through the elasticity of the elastic sealing rubber tube 107, so that the elastic sealing rubber tube 107 wraps the outer wall of the package, which is convenient for the subsequent sealing detection of the package.

A fourth motor 210 is fixedly installed at the bottom of the sealing detection rod 203. A threaded rod is fixedly installed on the fourth motor 210.

An electric push rod is fixedly installed between the support slider 207 and the sealing detection rod 203. A motor is fixedly installed on the support slider 207. A threaded rod is fixedly installed on the motor of the support slider 207. The threaded rod on the support slider 207 cooperates with the screw rod of the outer wall detection plate 208. A plurality of liquid transmission pipes 214 are fixedly installed, and the liquid transmission pipes 214 are connected to an external liquid pump. The liquid transmission pipes 214 are respectively connected to the top detection plate 209 and the outer wall detection plate 208. A plurality of coating hoses 216 are fixedly installed at the bottom of the top detection plate 209 and the inner side of the outer wall detection plate 208. The coating hoses 216 are used to apply a non-solidifying colloid detection liquid to the package. When the sealing of the package is insufficient, the air in the package is extracted from the gap through the negative pressure in the elastic sealing rubber tube 107, and bubbles are generated in the detection liquid blocked in the gap, so as to achieve the purpose of detecting the sealing of the package. The coating hoses 216 are connected to the liquid transmission pipes 214. After the elastic sealing rubber tube 107 wraps the catalyst package, the coating hoses 216 are opened. The electric push rod on the top of the dynamic detection carrier 102 drives the detection telescopic rod 201 to descend, adjusts the distance between the bottom of the sealing detection rod 203 and the package, and then starts the fourth motor 210 to control the top detection plate 209 to descend, so that the coating hose 216 contacts the top surface of the package, and the detection liquid is applied to the top surface of the package. At the same time, the electric push rod between the support slider 207 and the sealing detection rod 203 is started to drive the support slider 207 to descend, and at the same time, the motor on the support slider 207 is started to control the outer wall detection plate 208 to slide in the support slider 207, so that the coating hose 216 on the outer wall detection plate 208 contacts the side of the package, and then the third motor 202 is started to drive the sealing detection rod 203 to rotate, and the detection liquid is applied to the top and side of the package through circular motion.Then, the air inside the elastic sealing rubber tube 107 is extracted through an external air pump connected to the air extraction pipeline 215, and the air bubbles are observed in the test liquid on the package to detect the sealing of the package.

[0035] like Figures 1 to 12 As shown, a pair of arc-shaped support blocks 205 are longitudinally slidably installed at the bottom of the sealing detection rod 203, an electric push rod is fixedly installed between the arc-shaped support block 205 and the sealing detection rod 203, a plurality of arc-shaped detection plates 206 are longitudinally slidably installed at the bottom of the arc-shaped support block 205, a compression spring is fixedly installed between the arc-shaped detection plate 206 and the arc-shaped support block 205, a plurality of detection grooves are arranged at the bottom of the arc-shaped detection plate 206, a vibration detection rod 212 is fixedly installed at the top of the detection groove, an elastic vibration bead 211 is fixedly installed at the bottom of the vibration detection rod 212, a vibration membrane 213 is fixedly installed at the bottom of the detection groove of the arc-shaped detection plate 206, the vibration membrane 213 is used to detect whether the package is leaking when the detection liquid cannot be applied to the surface of the package, and the vibration membrane 213 and the elastic vibration bead 211 are fixedly installed. 1. Contact matching. When the catalyst packaging is special and cannot be tested by smearing the detection liquid, the electric push rod between the arc support block 205 and the sealing detection rod 203 is started to drive the arc support block 205 to descend, so that the arc detection plate 206 fits the packaging surface, and the third motor 202 is started to drive the sealing detection rod 203 to rotate slowly. When the packaging is not sealed well and air leakage occurs in the elastic sealing rubber tube 107, the gas leaked from the gap blows the vibration membrane 213 at the corresponding position to vibrate slightly, and at the same time drives the elastic vibration beads 211 in contact with it to bounce up in the arc detection plate 206, amplifying the vibration effect, and converting the vibration into an electrical signal through the vibration detection rod 212 to transmit it to an external receiving device, so as to detect the sealing of the packaging.

[0036] like Figures 1 to 12 As shown, a plurality of adjusting threaded rods 104 are longitudinally rotatably installed on the detection base 105, the screw rods on the adjusting threaded rods 104 are equipped with a detection support plate 103, the detection support plate 103 is used to support the catalyst package to be detected, a pulley is fixedly installed at the bottom of the adjusting threaded rods 104, the adjusting threaded rods 104 are interconnected by belts, a first motor 106 is fixedly installed on the detection base 105, the output shaft of the first motor 106 is fixedly connected to the adjusting threaded rods 104, and a cover plate 101 is fixedly installed on the top of the detection carrier plate 102 through a support rod.

[0037] Working principle: When it is necessary to test the sealing property of the catalyst package, first place the package to be tested on the test tray 103, then start the first motor 106 to drive the adjusting threaded rod 104 to rotate, and drive the test tray 103 to rise, adjust the height of the package to facilitate subsequent testing, then start the second motor 110 to drive the gear ring 109 to rotate, drive the adjusting ring 204 to descend, and open the bottom of the elastic sealing rubber tube 107, and at the same time control the test tray 103 to continue to rise, so that the package enters the elastic sealing rubber tube 107 and waits for testing.

[0038] When the package enters the detection position, the second motor 110 is started to rotate in the opposite direction, so that the adjustment ring 204 rises and returns to its original position, and at the same time, the outer wall of the package is wrapped by the elastic sealing rubber tube 107. Then, the electric push rod on the top of the detection carrier plate 102 is started to drive the detection telescopic rod 201 to descend, adjust the distance between the sealing detection rod 203 and the package, and use different methods to detect the sealing of the package as needed.

[0039] When the package will not be affected by the detection liquid, by starting the fourth motor 210 and the electric push rod on the top of the supporting slider 207, the top detection plate 209 and the supporting slider 207 are driven to descend to a suitable position, so that the coating hose 216 contacts the top and outer wall of the package, and then the third motor 202 is started to drive the sealing detection rod 203 to rotate, and the detection liquid is applied to the outer wall of the package. At the same time, the external air pump is started and the air in the elastic sealing rubber tube 107 is extracted through the exhaust pipe 215, so that a negative pressure is formed inside the elastic sealing rubber tube 107. When the package is not sealed enough and there is a gap, the air in the package will seep out through the gap, causing bubbles to form in the detection liquid outside the package, so that the sealing effect of the package can be intuitively detected.

[0040] When the packaging material is special and cannot be tested with detection liquid, or when no detection liquid is used for testing, the electric push rod between the arc support block 205 and the sealing detection rod 203 is started to drive the arc support block 205 to descend, so that the arc detection plate 206 contacts the packaging surface, and then the external vacuum pump is started to extract the air in the elastic sealing rubber tube 107, so that the inside of the elastic sealing rubber tube 107 becomes a negative pressure, and then the third motor 202 is started to drive the sealing detection rod 203 to rotate slowly. When there is a defect in the seal on the package, the air in the package is extracted by the negative pressure in the elastic sealing rubber tube 107. When the air in the package seeps out from the gap, the vibration membrane 213 is blown to vibrate, and the elastic vibration beads 211 amplify and convert the vibration into an electrical signal, which is transmitted to the external receiving device.
